Understanding MCP (Model Context Protocol) and GitHub Integration

What is MCP?

Model Context Protocol (MCP) is a revolutionary standardized protocol that enables AI agents to communicate seamlessly with various tools and services. Think of it like a universal translator:

• Without MCP: Each tool speaks its own language, making it difficult for AI agents to integrate with multiple tools.
• With MCP: All tools speak the same language, allowing easy integration and communication.

Real-World Analogy

Imagine having ten expert consultants, each speaking a different language:

• Without MCP: You'd need ten different translators
• With MCP: Everyone speaks a common language, making collaboration effortless

This standardization allows AI agents to:

• Connect to databases
• Interact with GitHub
• Access cloud services
• Manage files and documents
• And much more!
